36" x 24" full color laminated poster. "We can follow our dreams to distant stars...," declared President Reagan when he proposed this ambitious project in his 1984 State of the Union address. This poster provides a comprehensive overview of the program goals, how it got started, its various components, and its appearance when finished. The visiting Space Shuttle provides scale.

Fossils were a mystery for thousands of years; then a few pioneering scientists realized that they were the remains or traces of once-living organisms.
Well-known bone-type fossils are actually rocks, the result of a process called mineralization in which minerals replace decaying tissue. This process is shown and explained. All of the other fossil types are also explored.
The rarity of fossils is dramatically presented, and strange things sometimes mistaken for fossils are identified. There€™s an introduction to fossil expeditions and a summary of how fossils contribute to our understanding of the earth and life on it.
There is an especially helpful section on the relationships between fossils and geology. It covers the principle of original horizontality, the law of superimposition, the principle of faunal succession, the geological time scale, index fossils, relative dating, and absolute dating.
All of this is conveyed through detailed illustrations showing the processes, excellent photographs of representative specimens, and interesting and informative captions. This poster is a great aid to museum interpretive programs and is extremely beneficial in the study of both life and earth sciences.

This poster begins by defining a mineral. It then expands on that by exploring atoms, molecules, and crystal structure. The various crystal structures are explained. This is followed by an excellent summary of the mineral classes.
Mineral collectors and students want to identify their specimens. However, specimens of the same mineral can vary greatly in appearance, which can make that a daunting task. Identification is based on a number of properties.
This poster provides an outstanding introduction to those properties: hardness, habit, luster, cleavage, specific gravity, color, streak, and fluorescence. Illustrations are used to explain principles. Photographs of truly outstanding specimens are used as examples.

An ideal growing medium for annual and perennial flowers, vegetables and house plants. Composed of equal parts of shredded sphagnum peat moss and fine grade vermiculite plus just enough nutrients to sustain initial plant growth. Mixture will produce acceptable plants but for long term growing a balanced water soluble fertilizer is applied weekly. 4-Quart bag fills 35-3" pots.
Kimax® flasks for economy and versatility. These flasks are the choice for general laboratory usage. Tops are reinforced and tooled with a rounded finish, containing more glass to give them maximum mechanical strength. Body is thick-walled, with a long tapered outside contour to minimize chipping when struck or rubbed together. All flasks have durable white ceramic enamel scales to indicate approximate volumes at various levels, useful in measuring and mixing solutions where a high degree of accuracy is not necessary. Designed from ASTM Specification E1404, Type I, Class I requirements. Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements.
